EYEGLASSES- Specificati on of Letters Patent.

Patented Oct. 9, 1.906.

Application filed lugust 28. 1905. Serial No. 276,104.-

To all whom it may concern:

Be it known thatI, FREDERIGKWILLIiAM NoLTE, of the city of Victoria, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification'.

The object of my invention is to devise eyeglasses which look neat and light and which will hold on the nose without undue pressure; and it consists, essentially, in forming the eyeglasses with a hollow bridge, withand'in-conneoting the guards or nose-pieces to this wire in such a manner that they will gri the nose with a as hereinafter nitelyc aimed.

Figure 1 is a perspective view showing a pair of glasses eye constructed in accordance with my invention. Fig. 2 is a perspective View showing one of the nose-pieces and the bridge in section. Fig. 3 is a similar view showing a slight modification of the invention; Fig. 4 1s a similar view showing another modification. A Fi 5 is a sectional detail, on an enlarged sca e, showi naling of the nose-piece shownin 6 is an'enlarged sectional detail bridge is secured a wire B. This wire may with a cushion D, as shown in Fig.

continue right through the bridge, as shown in Figs. 2 and 4, or separate wires may be used, as shown in Fig. 3. If the wire be a close fit within thebridge, the iiictionwill be quite sufficient to hold the wires in place,

though the ends may easily be soldered or ot erwisei-s ecumd within the bridge. The outer end of, each wire B is bent to form the nose-piece 0, extending rearwardly from the, bridge.

This nose-piece may be a simple flattened loop, such as shown in Fig. 3, or. roughly triangular in shape and provided 2.1 The end of the wire is twisted round the main portion adjacent to the bridge and extended orward to form a s bein f ii u hed oii, tending to sprea preferab as shown. These'outwardly-exs may be grasped by the ers filie nose-piece apart when iii i s x de The torsional spring of the wire 13 and the grip E, the ends of thef-rl V y rounded or otherwise .Sired to Place theyeglasses on the nose. .1

spring in the nose-pieces" tend to press,the guards inwardly to grip the nose, and theyldo this with an effective elastic pressure, w makes the eyelasses quite secure, while very comfortab e to the wearer. To increase the torsional spring-of the'wire, it may bev doubled, as shown in Fig. 4, and the parts twisted together with a. right ha'nd twist from the center-to one end andwith a left-hand twisti from" the center toward the other end, so that the torsion is in diverse directions at the opposite sides of the brid e.

With the increased spring obtained b doubling and twisting the wire B, I find that I can dispense. with any spring in the noseguard, and ma therefore emplo the stiff nose-piece C s own in Fig. 4. his nosepiece, it will be seen, is provided with a holow ournal within the lower end of the bridge. .Through this hollow journal the wire is passed, and is suitably secured therein by soldering or otherwise.

In Figs. 4 and 5 I show a simple method, the wire having its end bent into a notch in the nose-piece after having :been passedthrou h the journal. of hol ing the twisted wire in the bridge is to fit in theloop left at the center where the I find a good method change in twist is made a small plateK.

This plate fitting tightly in the bridge cannot.

turn therein, and thus full-advantage may be obtained of the torsion of each half of the wire. The grip E is integral with the-nose-. piece 0.

In Fig. 6 I show in detail the preferable construction of the cushion'sho wn m2 and 4. The cushion is secured loose hole H in the nose-guard and-is provided with a head I ofgreater-size than the hole H. On the pin, between the nose-piece and the cushion, is placed a fine coil-s ring J which tends to retain-the cushion in t 'e position shown; but owing to the loose connection with the nose-piece and the yielding action of the spring the cushion will readily The cushion vDY may also be em I ployed with this nose-piece, as shown.

rod

to the inner end of a pin G, which is passed through a ily to the various shapes of noses with which view. to the left the fastened end of the wire they are employed.

In Fig. 8I show a preferred form of solid nose-piece. It is provided with a shoulder m, at which through a hole is inserted and fastened the end of the torsional spring-Wire B, whiehpasses through the bridge A. This end is bent at an angle to the spring-wire in the oridge, as is clearly shown in the upsidedown view to the right in Fig. 8. In the at the shoulder is indicated atb. This mode of fastening the end of the spring-wire to the nose-piece affords a good grip on the nose.

What I claim as my invention is 1. In eyeglasses a hollow bridge; a wire forming a spring, and rigidly held at oneend within the bridge; and a nose-piece connected with the wire, substantially as described.

2. In eyeglasses a hollow bridge; two wires twisted together and held Within the bridge, and a nose-piece connected with the outer end of the doubled wire, substantially as described.

3. In eyeglasses a hollow bridge; a wire held firmly at one end within the bridge and a nose-piece connected with the wire extending rearwardly and a finger-grip extending forwardly, substantially as described.

4. In eyeglasses a hollow bridge, two

' wires twisted together and held firmly at one end within the bridge, and a nose-piece connected with the outer end of the doubled wire extending rearwardly and a finger-grip ex tending forwardly substantially as described. 1 5. In eyeglasses a hollow bridge, a wire held-firmly at one end within thebridge, and

a nose-piece connected with the outer end of the wire and vertically journaled on the lower end of the bridge, substantially as described.

6. In eyeglasses ahollow bridge, two wires twisted to ether and held firmly at one end within the ridge, and a nose-piece connected with the outer end of the doubled wire and vertically journaled on the lower end of the bridge, substantially as described.

7. In eyeglasses a'hollow bridge, a wire held firnily at one end within the bridge, and a nose-piece connected with the outer end of the wire; a journal on the nose-piece having abearing within the lower end of the bridge, substantially as described.

8. In eyeglasses a hollow bridge, a wire held firmly at one end within the bridge, a

nosepiece connected with the outer end of the wire, a hollow ournal on the nose-piece having a bearin within the lower end of the bridge, the wireieingsecured within the hollow ournal, substantiall as described. v

9. In eye lasses a fiollow bridge; two wires twiste from the middle to one end with a right-hand twist and from the middle to the other end with a left-hand twist and rigidly held at its middle within the bridge; and a nose-piece connected with each of the outer ends of the doubled wire,'substantiall y as described. y

10. In eyeglasses the combination of hollow bridge A, spring-wire B, nose-piece (1 provided with shoulder m, the end of the springwire being bent at an angle and fastened at 1) near the shoulder, as described.

11. In eyeglasses a hollow bridge; nosepieces vertically journaled at the lower ends of the bridge; atorsion spring-wire held within the bridge and engaging the nose-pieces to impart a spring action thereto, substantially as described.
